Get possible_values of custom fields for non-admin users
In #11159 support for getting the definition of custom fields was added to the API. This call is only available to admin users. Problem is for custom fields with List-Format (and I guess with KeyValuePairs), as a non-admin-user it's not possible to retrieve the "possible_values" or enumerate key-values.
I'm wondering if this could be added, maybe as an enhancement of #33301?
